Version 1.2 © 2012 Steve Cooley ( http://sc-fa.com , http://beatseqr.com , http://hapticsynapses.com © 2021 Matthias Ansorg ( https://ma.juii.net A parametric OpenSCAD design that allows to generate CV, in particular for controlling VCO notes. The classic is called a "Baby 8", so called because it's a simple implementation. Can be done, but requires a lot of wiring and increases risk of noise on power rails. Things best left to external modules: CV-controlled CV offset module - add a switch to set output voltages. (10) One potentiometer per step, to set output voltages. (10) - One potentiometer for internal clock rate. One SPDT switch per step, to set output voltages. (10 One SPDT switch to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). Momentary-normal-off pushbutton to manually step. SPST switch per step, to enable/disable gate per step.
